Low said: “Chelsea’s doctors estimate he will not be able to play for two to three more months.

“But Michael is much more optimistic and expects to play sooner. For us, Chelsea’s decision isn’t justifiable.

“I discussed it with Michael and he could not fully explain Chelsea’s decision to me,” said Low.

However, Chelsea have dismised the specualtion as unfounded.

A statement from the club read: “We hope Michael’s recovery is as quick as possible.

“We hope Michael returns to full training soon so that he will then be available for the Champions League latter stages.

“There is no other reason for the decision and suggestions to the contrary are unfair on both Michael, who is attempting to get fit as soon as possible, and our medical team in whom we have every confidence.”
